Fig. 9 is a view principally in vertical gagement with the member a by means of a Section from front to rearof the machine to lover a, which is pivoted at e, and by means of aforked end and rolls engages the movable member 6 of the clutch. This lever has a latch 6 which is held in line with a cam-stop a on the inner face of the gear (Z and is adapted to be moved out of engagement with said cam-stop by means of a treadle e and suitable connection. Upon the disengagement of the latch the spring 6 moves the lever c and the movable member (2 of the clutch into engagement with the driving member of the clutch,and said engagement is maintained until the gear d making a full revolution, comes into contact with the latch,which meanwhile is moved into position to be operated by it to draw the lever and the movable member of the clutch away from the driven member of the clutch and in opposition to the actuatingspring. In the section (Z of the pressure-head there is arranged a cross-head F, which has a movement in the section (1 independent of it, and which carries or supports a block f, from which extends upwardly, to enter the holes d, the gang of awlsf. This cross-head F is con nected with the upper cross-head B by the connecting-rods f f, (see Fig. 4,) so that it moves in unison with the cross-head B.

G is the nailcarricr. It is moved into and out of operative position positively and automatically in any desired way, and in Figs. 1, 2, and 5, I have shown it as operated or moved into a position by means of a cam g upon a vertical shaft g. This shaft is operated from the power-shaft by means of .a bevel-gear connection between it and the short vertical shaft and a small gear-g" upon the upper end of this short shaft,which engages with the larger gear upon the vertical shaft :9.

In Fig. 9, I have represented the nail-carrier as moved into position by means of a lever G, pivoted at g and operated by a cam g on a horizontal shaft g connected by a gear with one of the gears upon the shaft d In both cases I have represented the cam g and g as constructed to move the nail-carrier into operative position. The nail-carrier is moved out of operative position by means of springs 9 In the construction represented in Figs. 1, 2, and 5 the springs serving to throw out or withdraw the nail-carrier plate immediately after the drivers have lifted from its holes independently of its operative cam, so that it can be quickly removed from its operative position over the templet to its position to receive its load of nails, and in a time quicker than it can be moved by the cam. This is necessary, because in the operation of the machine it is essential that it be stopped immediately after the ends of the drivers have cleared the holes of the nail-carrier, and immediately upon said clearing of the drivers the nail-carrier must be quickly moved back to the position to receive its nails.

In Fig. 9 the nail-plate-withdrawing spring is represented bearing against the lever Gr. Of course the nail-carrier could be moved into and out of operative position by hand, but I prefer to move it automatically.

In Fig. 10, I have represented, in lieu of the former D, a last or work-support for a boot or shoe mounted to be operated by the pressure-head.

The operation of the machine is as follows: The stop-motion is adjusted to stop the machineupon its upward movement when the ends of the drivers have cleared the upper surface of the nail-carrier plate G. The cam (Z then immediately moves the former or last or work-support rapidly upward into the cavity of the solid die, if one be used, and against the under surface of the templet-plate and holds it in such position. Meanwhile the cross-head B is moving upward, thereby causing the lower cross-head F and the gang of awls f to be moved upward also. The former or last or work-support comes to rest before the cross-head B reaches its highest position, and this causes the awls to be driven from the surface of the former upward through the compressed or compressed and molded heel or through the soles and heel to any extent required. As a rule, I prefer to drive them through the heel sufficiently to cause their ends or points to project or extend into the holes 0 of the templet. The cross-head B then moves downward, moving the lower cross-head F and the awls f downward in relation to the heel and in relation to the last or work-support .or former, the last or work-support or former still remaining in position to hold the heel in the mold, if one be used, and against the under surface of the templet. The nail-carrier G, having its holes filled with nails either by hand or by automatic feeding .devices II, is moved into position over the templet with its holes in register with the holes 0 during the upward and downward movement of the crosshead B, and the drivers I) enter the holes of the nail-carrier and force the nails therefrom through theholes a into the holes in the heel blank formed by the awls, the nails and drivers following the downward movement of the awls, and the nails being driven into the heel-blank sufficiently to attach it to the soles of a boot or shoe, if one be used, or into the heel-blank only, leaving the ends of the nails ex tending from the tread surface thereof. Immediately-upon. the driving of the nails, the heel-former or last .or work-support is permitted to move downward by the cam (7, thereby permitting the cross-head B, by employment of drivers Z) of sufficient length and its continued descent, to force the heelblank from the die and the portion of the nails which remain in the holes 0 of the templet from the holes. Of course this ejecting movement of the drivers is only necessary where the organization is used for making a loaded heel-blank or a loaded molded heelblan-k. The cross-head B then lifts slightly sufficient to bring the ends of its drivers above the nail-carrier plate G and permit the nail-carrier plate to be moved backward or into position. to be loaded.

The position which the parts bear to each other upon the starting of the machine-that is, after the heel has been placed in position upon the former-4s represented in Fig. 4. The position which theybear to each other at the end of the compressing or molding action upon the heelthat is, after the heel has been lifted upward by the former into the solid die and is compressed, and also after the awls have been moved upward to the heels in the former and into the heel-blankis represented in Fig. 2.

The relation which the parts bear to each other after the compression and pricking of the heel blank and during the driving into the heel-blank of the nails from the nail-carrier is represented in Fig. 3. And the further action of the drivers in disengaging the compressed molded and loaded heel-blank from the mold is represented in Fig. 6.
